Hello,

I know what I'm requesting might not be able to be done due to framework and SoC or hardware limitations, but I'll throw it out there anyway. Since there is some effort done to high speed imaging @ 120fps with Magic Lantern, I thought my requirements could be filled with a Magic Lantern powered Canon camera! Basically I am asking if it would it be possible to mimic a finish line camera by reading a single line of the image sensor at 400fps to 2000fps with Magic Lantern? I'm no software nor a hardware expert, but for what I know, maybe it could be possible to read a single line from the camera at several hundred frames per second and either create a video file from the capture of the single line. A image file could work fine too, since the actual required bandwidth isn't that great by modern standards. I imagine maybe the 2nd option would be easier to implement because one wouldn't need to tune the feature to work with a video encoder. Perhaps even RAW video could be shot.

For use cases there are the obvious; cycling races, winter sports, motor racing and athletics. Then there are also more ambiguous uses, for example industrial or production line usage, especially if you can somehow pull the camera feed live. I imagine it wouldn't be too difficult to take it even further than this, even as a timing equipment, since some Magic Lantern supported camera's support a GPS receiver, which could be used for accurate timing of the image/images. I understand timing several hundred images per second would get a lot more difficult, but even getting an accurate time for just the first image would make the camera feasible as accurate timing equipment.

This kind of implementation, even if implemented just half way @ 500fps would dramatically reduce the cost of acquiring and using a high speed line scan camera (finish line cameras with certified hw & sw cost 7-15k$, and industrial line cameras are in the same range)

Thanks
